Runit Dome is a concrete structure located on Enewetak Atoll in the Marshall Islands. It serves as a cap for radioactive waste.

Visual Characteristics

The structure is a circular concrete dome, approximately 18 meters in diameter and 7 meters high. Its surface is weathered concrete, showing signs of age and exposure to the elements. The dome is situated on a coral island, surrounded by vegetation and the Pacific Ocean.

Location & Access Logistics

Historical & Ecological Origin

Runit Dome was constructed between 1977 and 1980 by the United States Department of Energy. Its purpose was to contain approximately 85,000 cubic meters of radioactive contaminated soil and debris resulting from nuclear weapons testing conducted on Enewetak Atoll between 1946 and 1958. The waste was consolidated and covered with the concrete dome.

This period offers the most favorable weather conditions with less rainfall. Access is dependent on sea conditions, which can be rough outside of calmer periods.

Facts & Legends

A unique aspect of Runit Dome is that the concrete used in its construction incorporated radioactive materials from the testing sites, effectively making the dome itself a repository of some of the contamination it was designed to contain. Local accounts sometimes refer to the dome as the "Tomb of the Nuclear Dead."
